Labcenter Electronics Proteus PDSPRJ File Parsing Out-Of-Bounds Write Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Labcenter Electronics Proteus. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the processing of PDSPRJ files. The issue results from the lack of proper validation of user-supplied data, which can result in a write past the end of an allocated buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-25719.
Analysis
Out-of-bounds write in Labcenter Electronics Proteus PDSPRJ file parser enables unauthenticated remote code execution with high integrity impact. Exploitation requires user interaction (opening malicious PDSPRJ file or visiting attacker-controlled page). …
